Infection control measures and proper hand washing techniques. Hand washing has to be done to prevent the growth of microorganisms on the nails, hands, and forearms. When hands are visibly dirty or contaminated with proteinaceous material or are visibly soiled with blood or other body fluids, wash hands with soap and water, if hands are not visibly soiled, use an alcohol-based hand rub for routinely decontaminating hands. Wash hands before eating and after using a restroom. Wash hands for at least 15 seconds, covering all surfaces of the hands and fingers, rinse hands with water and dry thoroughly with a disposable towel, use towel to turn off the faucet, use hand lotions or creams to minimize the occurrence of irritant contact dermatitis associated with hand antisepsis or hand washing.
